Yep I went through the same migration for 100’s of sites on my forms handling about 4 years ago. So glad I did.
The problem for me was that even if Webflow fixed everything regarding SPAM handling and individual form submission control, there were still issues regarding the email notifications as well. Top 3 for me were (1) the unsubscribe link (2) the inability to handle line breaks in textarea content, and (3) the forced display of checkboxes even when they’re unchecked.
But I do know the Webflow team is working hard to improve these areas, and I’m looking forward to when I can switch back to native handling at some point.
Regarding the DNS changes, yep I get that too. I’m glad this is the first time I’ve seen a DNS change on existing sites in 8 years of using Webflow. Also, the new O2O configuration is worth it for all my reverse proxy setups.
